I am setting up a base station with a 20 MHz bandwidth. I get that value with AT+QENG=“servingcell”, but not with AT+QSCAN. What could be causing this?

With AT+QENG=“servingcell”:
Standard:“NR5G-SA” State:“LIMSRV” DuplexMode:“TDD” MCC:999 MNC:70 CellID:001234501 PCI:500 TAC:1 ARFCN:664992 CenterFreq:3974.88MHz Band:77 DL_Bandwidth:20MHz RSRP:-88dBm RSRQ:-10dB SINR:27dB SCS:30kHz SRXLEV:51dB
FreqRange:3964.88MHz-3984.88MHz

With AT+QSCAN:
Standard: NR5G | MCC:999 | MNC:70 | ARFCN:664992 | CenterFreq:3974.88MHz | PCI: 500 | RSRP: -dBm | RSRQ: -11dB | SRXLEV: 52dB | SCS: 30kHz | Cell_ID:001234501 | TAC: 1 | Bandwidth: 51MHz | Band: 77 | FreqRange:3949.38MHz-4000.38MHz |

Good morning,
How could I install it? Do I need qfirehose?

Dear @Carlos_CM
If use linux, you need use Qfirehose to upgrade.

Good morning, I have updated it, but at+qscan continues to give me strange results for the bandwidth. I have also reported this in the following issue: Strange BW result in AT+QSCAN
Thank you very much!
